context_page_description: In chemistry, aluminium(I) refers to monovalent aluminium in both ionic and covalent bonds. Along with aluminium(II), it is an extremely unstable form of aluminium.
  While late Group 3 elements such as thallium and indium prefer the +1 oxidation state, aluminium(I) is rare. Unlike late Group XIII elements, aluminium does not experience the inert pair effect, a phenomenon where valence s electrons are poorly shielded from nuclear charge due to the presence of filled d and f orbitals. As such, aluminium (III) is the much more common oxidation state for aluminium.
  Aluminium(I) compounds are both prone to disproportionation and difficult to prepare. At standard conditions, they readily oxidize to the aluminium(III) form.
context_section_description: In 2018, Liu et. al explored the chemistry of aluminium (I) with β-diketiminato ligands, widely used ligands with immense versatility in electronic and steric properties. These aluminium (I) complexes have immense potential for small molecule activation.
  Synthesis
  β-diketiminato aluminium alkyls and aluminium halides are synthesized by adding a trialkyl aluminium compound to the initial β-diketiminate ligands, adding iodine, and the reducing with potassium.
